Rotary Potentiometers, Rheostats

A rotary potentiometer, also known as a rheostat, is a device that creates an electrical resistance based on a rotational movement. It is typically used to control the resistance of a circuit, to regulate voltage and current, or to set the level of an audio signal. The PTD901-2015K-B102 is a type of rotary potentiometer designed for a variety of uses.

The device consists of a resistor element wrapped around a central axle. As the user turns the axle, the resistor moves along its length, changing the circuit’s resistance accordingly. There are two terminals on the device, called adjustable and fixed, which correspond to the two ends of the resistor element. By connecting the adjustable terminal to the circuit’s ground, the resistance of the circuit can be adjusted by simply turning the axle, which causes the adjustable terminal to move along the resistor element.

The PTD901-2015K-B102 uses a sliding contact element instead of a rotary axle, allowing for greater resolution and higher accuracy than traditional rotary potentiometers. This makes it an ideal device for precision applications, such as in lab equipment or in control systems. Its resistance range is 0-500 kilo ohms with a working voltage of up to 400 V. It can be used to create a variable resistor with a highly stable resistance.

The PTD901-2015K-B102 is a common component in many popular electronic devices, such as audio amplifiers, power tools, receivers, and other devices that require a variable resistance. It is also used for signal processing, isolation circuits, and for controlling motors. The device is constructed from high-quality materials to ensure reliability and long-term use.

The PTD901-2015K-B102 is a versatile and reliable device that can be used in a variety of applications. Its adjustable resistance makes it perfect for controlling temperatures, regulating current flow, and tuning audio signals. It is an economical and efficient component, and can be used in both industrial and consumer applications.
